I have an app that I’m working on where I use labels for the CheckBoxes and RadioButtons to allow me to change the text colors. I then handle MouseDown/MouseUp as if the user clicked the control. At certain points, I disable the control and its associated label. However, I’ve now discovered that even though the Label is disabled, the MouseDown and MouseUp events are still raised causing runtime errors.
In a project, I have a Canvs where KeyDown / KeyUp Events were not fired
After some days, I created a simple project with a Canvas and KeyDown / KeyUp Events. It appears they works there. After a long quest, I, at last finished to discover the difference between the two projects and make the Events to be fired.
Boring process, but now I can remove the Canvas1.Backdrop image !.
